Cannabis Compound Identification
Common Name4-Methylquinoline
Description4-Methylquinoline, also known as Lepidine or cincholepidine, belongs to the class of organic compounds known as quinolines and derivatives. Quinolines and derivatives are compounds containing a quinoline moiety, which consists of a benzene ring fused to a pyridine ring to form benzo[b]azabenzene. 4-Methylquinoline is a methylated derivative of quinoline in which a methyl group substituted at position 4. It exists as a clear, colorless oil that is only slightly soluble in water. 4-Methylquinoline has a sweet, floral, oily and slightly burnt odor and a sweet, floral, slightly burnt taste. It is used in the cosmetic industry as a perfuming agent. It is found naturally in peppermint oil and garden cress seeds. 4-Methylquinoline (4-MeQ) has been shown have extraordinarily high mutagenicity when compared to quinoline and isomeric methylquinolines (PMID: 8860954 ). 4-Methylquinoline is formed during the combustion of cannabis and is therefore a constituent of cannabis smoke ( Ref:DOI ).
